Coils consisting of a number of turns of wire and connected in sequence are run up the inside of an elevator shaft. The elevator itself is fitted with a vertical row of magnets on the outside of the cabin that will pass over the coils and generate electricity on every elevator ride. This can be used
to charge a (12V?) battery bank for emergency lighting use etc.
